Early feminists were against abortion. Later feminists, including Planned Parenthood, were too. (They thought pregnancy prevention was important, but distinguished between preventing a pregnancy and getting rid of one that was already there.)
Indeed, Anthony and Stanton believed something like the reverse: give women the right to vote so that women might have the power and the influence to do away with the ghastly practice of abortion. Here is Stanton herself: “There must be a remedy for such a crying evil as this. But where shall it be found, at least where begin, if not in the complete enfranchisement and elevation of women?”
The early American feminists presumed that the evil of abortion would be abolished by the elevation of women. Today’s feminists maintain that women’s elevated status depends upon easy access to abortion.
